Definitions

  • the present invention relates to TV programs, and more specifically to a method and system for assisting the watcher of a TV program in catching information or explanation about words used in a current program.
  • the watcher of a TV program may not understand some words that he hears or reads. For example, some words used in a scientific TV program may not be understood by all the watchers. Further, backgrounds of the watchers are different. So, the words that are not understood are not the same for all the watchers of a TV program.
  • Such a channel broadcasts, in loop, explanation about topics chosen by the broadcaster and contained in the TV program.
  • a drawback is that the explanations are broadcasted as goes the TV program and, when switching to the explanation channel, the watcher has to read explanation of other topics before the information he is looking for comes again in the broadcasted loop. During that time, the normal TV program goes on and the watcher looses information.
  • the broadcasted explanation channel cannot be personalized for each watcher. Further, it is restricted to topics rather than words due to the limited number of available channels for broadcasting explanation, and a same channel may contain explanation about several TV programs, which is not useful.
  • a purpose of the present invention is to provide a method and a system for automatically extracting words of a TV program which may not be understood by the watchers, and to give them the possibility of obtaining an explanation for some of these words.
  • Another purpose of the present invention is to provide a computer based apparatus and method to be associated with a screen adapted to display TV programs for giving a watcher the possibility of getting information and/or explanation about a word that he hears or reads in the TV program and about which he wants more information.
  • Another purpose of the present invention is to provide a system and method which do not require the watcher to type the searched words on a keyboard.
  • the present invention provides a computer based method for generating information about words used in a TV program or the like, comprising the steps of:
  • the words appearing in a TV program are extracted on the basis of their number of occurrences to determine the words for which an explanation will be proposed.
  • the window of occurrences is limited to two predetermined thresholds which may be fixed by the manufacturer of the system, downloaded by the broadcaster into the device, or chosen by the watcher.
  • an auto-adaption of the windows of occurrences is provided.
  • the low and high thresholds of the windows are automatically adapted in real time as goes the TV program.
  • Such an auto-adaptation can be based on a maximum predetermined number of words to be displayed. It can also be based on percentages of words among the total number of extracted words.
  • the extracted words are chosen among a pre-list of words stored with their occurrences in the TV program and in which predetermined common words are already eliminated.
  • the extracted words of a TV program are preferentially displayed on at least a dedicated line superposed to the TV program, in the form of a list of words.
  • the list is preferably a scrolling list for displaying more words.
  • the watcher may use any selection device like a keyboard or a pointing device to select an extracted word for which he wants information.
  • the information or explanation about the selected words may originate from different sources.
  • a computerized dictionary which can be internal or external to the system.
  • an external dictionary is preferred because it allows an updating of the information.
  • the external dictionary may be constituted by a computerized dictionary available on the Internet or on any specific network.
  • the search of the explanation about a selected word in a dictionary takes not only into account the word itself but also the field in which it was used. Indeed, a same word may have several meanings depending on the field.
  • dialogs of TV programs are also broadcasted in written format broadcasted to provide “Teletext” information.
  • the Teletext format which is present in the flow of the TV program is part of a specific sub-channel associated with each broadcasted TV channel. According to a preferred embodiment of the present invention, this available Teletext information is used to search and extract the words considered as relevant to be displayed for selection to the watcher.
  • FIG. 1 schematically represents the main elements of one exemplary embodiment of the system of the present invention
  • FIG. 2 represents a TV image illustrating one exemplary embodiment of the method according to the present invention
  • FIG. 3 is a flowchart of the main steps of one exemplary embodiment of the method of word extraction according to the present invention.
  • FIG. 4 is a flowchart of the main steps of one exemplary embodiment of catching word information according to the present invention.
  • one exemplary embodiment of a system for generating information about words used in a TV program includes a general purpose TV set 1 (or any analog system like, for example, a personal computer equipped with a tuning card).
  • the TV set comprises a screen 2 and the conventional equipment to receive and display TV programs and, for the implementation of the present invention, a processing unit 3 .
  • the processing unit 3 may be a circuit dedicated to the implementation of the present invention or a general purpose central processing unit like a CPU of a personal computer and is associated with the necessary elements (memories, I/O devices) to execute a program implementing the method of the present invention and store the corresponding data.
  • TV set 1 is linked to a reception element 4 which might be an antenna or any connection to a wired or wireless broadcasting network and, preferably, comprises an access to Internet (WEB) 5 .
  • a reception element 4 which might be an antenna or any connection to a wired or wireless broadcasting network and, preferably, comprises an access to Internet (WEB) 5 .
  • WEB Internet
  • Such an access may be through a telephone line 6 or any conventional link.
  • the TV set 1 is equipped with a selection tool to be used by the watcher for selecting the words for which he wants more information as it will be disclosed later.
  • the selection tool may be a keyboard 7 or a pointing device like a mouse 8 .
  • Keyboard 7 and/or mouse 8 may communicate with the central processing unit 3 of the TV set through a wired 9 or wireless 10 link.
  • the selection tool may be included in the TV set, or may correspond to conventional buttons 11 of the TV set or of a remote control device (not shown) re-affected to implement the invention.
  • an image I displayed on the TV set 1 comprises, for what concerns the invention, three areas (other areas may be provided in the screen, for example in a multi-windows display on a PC screen).
  • a first area A 1 corresponds to the part of the screen dedicated to displaying the TV program.
  • the area A 1 preferably occupies the full image I.
  • the words W 1 , W 2 , . . . , Wn extracted automatically from the TV program are displayed, preferably on a scrolling form, on a second area A 2 .
  • Area A 2 may comprise several lines (or columns) but preferably corresponds to a single line (or column) of the screen, scrolling the words W 1 , W 2 , . . . , Wn.
  • a third area A 3 of the image I is dedicated to displaying the information or explanation collected according to the invention about a word selected by the user.
  • the area A 3 is preferably a temporary area. In other words, the surface of area A 3 is affected to the area A 1 for the TV program except during the time necessary to display information about selected words.
  • FIG. 3 represents a schematic flowchart of the steps of generating the scroll line A 2 of FIG. 2 , according to a preferred embodiment of the present invention.
  • the Teletext information associated with the TV program is used to get the exhaustive list of words of the TV program.
  • voice recognition means may be used to identify all the different words pronounced by the persons appearing in the TV program.
  • the first step of the method of the present invention is to obtain a list of words to be processed, i.e. a pre-list of words among which the system will extract and update, in real time as the TV program goes on, the words to be displayed in area A 2 for selection. Therefore, after having separated the words from the Teletext format (step 20 , WORD SEPARATION), the system extracts the current word (step 21 , CURRENT WORD).
  • a list of common words is pre-established and stored in a memory of the system for containing the words which are to be considered obviously as irrelevant whatever will be the TV program (for example the common verbs, articles, conjunctions, etc.).
  • the current word is searched in that list (test 22 , COMMON WORD).
  • the system increments by one its number of occurrences, selects the next word (bloc 23 , NEXT) and returns to the bloc 21 for the new current word.
  • the current word is taken into account (bloc 24 , STORAGE OR UPDATING COUNT) in the pre-list of words to be processed in order to determine their relevance.
  • the pre-list contains also the number of occurrences of the stored words. If it is the first occurrence of the word in the TV program, the current word is added to the pre-list. If the word is already present in the pre-list, its number of occurrences is incremented.
  • the system determines if the current word has to be considered as relevant (bloc 25 , RELEVANT?). If yes, the scroll line (area A 2 ) is updated to incorporate the current word (and eventually suppress another word from the extracted list).
  • the relevance of a word is based on the number of occurrences of that word in the TV program.
  • the system uses two thresholds between which the number of occurrences is considered as representing a relevant word. Accordingly, the words that appear very seldom are not selected as a watcher will not be interested in words that occur rarely. Also, the words that occur very frequently are eliminated as such words are likely to be common words or words that are well explained in the TV program of interest.
  • the two thresholds define a window of numbers of occurrences for relevant words.
  • the two thresholds are predetermined, for example, fixed by the manufacturer of the system, downloaded by the broadcaster into the device, or chosen by the watcher.
  • the thresholds are updated along with the TV program, i.e. the number of occurrences determining the relevance of the word is modified as goes the TV program to be auto-adapted to the size of the pre-list which grows up along with the TV program.
  • the first displayed words may appear as irrelevant for the watcher. However, words which are irrelevant will quickly disappear from the scroll list due to the auto-adaptation of the thresholds.
  • the auto-adaptation is based on a number of words to be displayed on the screen. For example, if the number of words to be displayed is twenty, the list of extracted words contains the twenty words of the pre-list which are central in the pre-list when sorted by number of occurrences.
  • the window of relevant numbers of occurrences corresponds to intermediate values of occurrences contained in the pre-list after eliminating a percentage of the less and most frequent words with respect to the total number of words of the pre-list. For example, assuming that the percentages are thirty percent for the less frequent words and fifty percent for the most frequent words, and that the current number of words contained in the pre-list is 110, the thresholds correspond to number of occurrences of the words of rank 33 and 55 of the pre-list sorted by number of occurrences increasingly.
  • the list of extracted words is updated and the display of area A 2 is also modified (bloc 26 , UPDATE SCROLL).
  • the system goes directly to the step of updating the thresholds (bloc 27 , UPDATE THRESHOLDS) for taking into account the increase of number of word occurrences.
  • the thresholds are not updated for each loop of the method (i.e. for each word processed) but periodically after a predetermined number of words.
  • the list of extracted words is also updated based on the time of presence of the words in the scroll line, to eliminate the too old words.
  • FIG. 4 represents a schematic flowchart of the steps of catching word information according to a preferred embodiment of the present invention.
  • the user may select a word (step 30 , WORD SELECTION) for which he wants a definition or more information.
  • the system of the present invention downloads the required definition (step 31 , DOWNLOAD DEFINITION) and displays the information (step 32 , DISPLAY) on the screen in the area A 3 .
  • the duration of the display of information may be prefix and/or the display can disappear when the watcher presses a dedicated button.
  • the TV set is linked to a local dictionary (that embodiment applies in particular to a personal computer) and the definition of the words is searched in that dictionary.
  • one provides a link to an external network (for example, Internet) to download the information about the word.
  • an external network for example, Internet
  • the search engines to be used for searching information about the words are pre-selected in order to avoid too long search for each selected word.
  • one uses a specific dictionary prepared by the broadcaster and available, for example, on a specific network or on a specific broadcasted channel.
  • the word selection is, for example, performed by the watcher either through a mouse 8 and a corresponding pointer on the screen, or through the keyboard 7 and more specifically its arrow buttons.
  • the dictionaries or encyclopedia used to find the information relative to the selected words may be any type of dictionary.
  • the broadcaster may include in the flux of Teletext information about the field or domain of the TV program allowing the search engine of the system of the present invention to select the correct meaning of a selected word.
  • the information relative to the field can also be used to select some specific dictionaries according to the topics of the TV program.
  • An advantage of the present invention is that it gives more information to a watcher of the TV program with customized information. Indeed, only if there are some words that a watcher does not understand, the third area A 3 of the screen will appear to display the desired information.
  • Another advantage of the present invention is that the relevant list of words displayed on the screen is updated in real time. Such an updating not only concerns adding some supplemental words, but also suppressing other words either because these words are out of the selecting window or because the words are present for a too long time.
  • Another advantage of the present invention is that the auto-adapting of the thresholds gives a system which can work from the beginning to the end of a TV program.
